删除，修改磁贴

磁贴通知

            var toast = ToastNotificationManager.GetTemplateContent(ToastTemplateType.ToastText01);

            var textNodes = toast.GetElementsByTagName("text");

            textNodes[0].InnerText = "呵呵呵";
            textNodes[1].InnerText = "你是猴子请来的救兵吗?";
            textNodes[2].InnerText = "呵呵呵";

            var Message = new TileNotification(toast);
            TileUpdateManager.CreateTileUpdaterForSecondaryTile("My_Title").Update(Message);
　　

HttpClient

            string url = "http://www.baidu.com";
            HttpClient client = new HttpClient();
            string responce = await client.GetStringAsync(url);

Weather天气实战

利用GPS获取手机坐标（经纬度）

            var geo = new Geolocator();
            var P = await geo.GetGeopositionAsync();
            var Po = P.Coordinate.Point.Position;

百度地图API获取位置信息

            string AppId = "XTTNdkZYIFCIqKVW1vfYUID3eWOgizwC";

            string Type = "json";

            string Url = "http://api.map.baidu.com/geocoder/v2/?ak=" + AppId + "&location=" + Po.Latitude + "," + Po.Longitude + "&output=" + Type + "";

            HttpClient client = new HttpClient();
            var json = await client.GetStringAsync(Url);

            JsonObject jsonRes = JsonObject.Parse(json);
            var City = jsonRes.GetNamedObject("result").GetNamedObject("addressComponent").GetNamedString("city");

百度天气接口 获取天气信息

            string WeaApi = "http://api.map.baidu.com/telematics/v3/weather?location=" + City + "&output=json&ak=" + AppId;

            var WeatherJson = await client.GetStringAsync(WeaApi);
            Info i= JsonConvert.DeserializeObject<Info>(WeatherJson);
            this.DataContext = i;

天气信息 Info Class

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;

namespace Weather

  public  class Info
    {
        public int error { get; set; }

加载前

Pro.IsActive=True;

加载完毕

Pro.IsActive=false;
